DEEP-WELL OUTFIT.

Specification of Letters Patent.

Patented Aug. 10, 1915.

Application filed June 13, 1912. Serial No. 703,537.

To all whom it may concern Be it known that I, CLARENCE L. PARKER, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles .and State of California, have invented a new and useful Deep-Well Outfit, of which the following is a specification.

This invention has reference to improvements in deep well outfits, and its object is to provide a means which may be installed in the derrick over a well for suspending sections of the sucker rod, and its object is to provide means whereby the rods may be kept st night while out of the well and in position for ready handling whether being removed from the well or placed therein.

Sucker rod sections are of comparatively short length and the lengths are-unitedby couplings, so that in a deep well. such as an oil well, many sucker rod sections are united end to end, for the pump cylinder is lodged deep in the well. It is sometimes necessary to remove the pump piston or even the pump cylinder and for such purpose the sucker rod must also be removed; The usual custom as heretofore p "actised has been to drag the rod sections out of the derrick as they are removed from the well and lay them lengthwise oneon the other. The sucker rods may be uncoupled at alternateor more distant couplings or' even at each coupling, and there is great liability of the couplings becoming wedged in between the rods in the hoisting and the rod sections are thereby easily bent or kinked. Such a bent rod is notonly ditlicult to couple to the remainder of the rod when being replaced in the well:

but a straight sucker rod willwear longer than a crooked one and will also cause less wear on the tube, besides offering less resistance. All these features count in both time and labor, and, therefore, in money saved. A

In accordance with the present invention the hanger device is suspended from the top of the derrick intothe interior thereof for an appropriate distance. and this hanger device contains a number of sockets or receptacles for the corresponding ends of the sucker rod sections. so that on the removal of a sucker rod from the well each section or group of sections removed may be lifted into the hanger device in order to there re-" damage and also main without liability of out of the way until again wanted.

providing the hanger device with a suitable number of receptacles or seats for the rod sections, the entire sucker rod may be accommodated and when again wanted the sections are in convenient reach of the operator to be readily screwed one after the other in order on to the portion of the sucker rod already being inserted into the well tubing without liability of bending or kinking, and consequently the rod may be maintained straight and in the most effective working condition, even though repeatedly removed from the well and replaced therein.

The invention will -be best. understood from a consideration of the following dctailed description, taken in connection with the accompanying drawings forming a part of this specification, with the further understanding that while in the drawings different emlmdimeuts of the invention are illustrated, the invention is susceptible of other practical embodiments, wherefore it is not confined to any strict conformity with the showing of the drawings, but may be. changed and modified within such limits as do not mark any material departure from the scope of the invention.

In the drmvings:'Figure 1 is a vertical section through a well derrick showing the invention applied. Fig. 2 is a vertical section through the portion of the hanger designed to directly receive the ends of the sucker rod sections and drawn to a larger scale than Fig. 1. Fig. 3 is a section on the line 3-3 of Fig. 2 and showing some sucker rod sections in place. Fig.4 is a vertical section through another form of sustaining device for the sucker rod sections. Fig. 5 is a fragmentary plan view of the structure shown in Fig. 4.

Referring to the drawings there is indicated in Fig. 1 a derrick 1, such as is used in connection with deep wells. particulm-ly oil wells. but no attempt is made to show the derrick in any particular detail. since the special structure of the derrick does not enter into the present invention. The derrick is shown as associated with a well casing that end only of the casing projecting above the ground being indicated. and here again no attempt is made at a showing of special structure.

The derrick is indicated as provided with crown blocks 3, rope sheave 4, tubing line 5 and bull wheel 6, while the well casing 2 is shown as provided with a casing head 7 and inner tubing 8. The tubing rope carries a hook 9 sustaining an elevator 10 for a sucker rod made up of sections 11, and these sucker rod sections terminate in screw ends '12 which, when the sucker rods are joined together, are united by couplings 13.

r The structure so far described may follow the usual practice in deep well outfits so far as the present invention is concerned, and, therefore, needs no particular detailed description.

Adapted to the derrick is a hanger rod 14 or more than one such rod in accordance with the particular construction employed, and each rod 14 has one end formed into a hook 15 adapted to engage over one of the crown blocks 3 in such manner that the rod or rods will hang pendently therefrom. The derricks are customarily of considerable height, which height is much more extensive than the length of a sucker rod section and may be greater than two sucker rod sections joined together.

Sustained by the lower ends of the hanger rods 14 when two such rods are employed is an elongated receiver frame in the form shown in Figs. 1, 2 and 3, and best shown in Figs. 2 and 3. This frame, which may be in the form of a single casting. has enlargements 17 at the ends each with a passage therethrough for a respective one of the hanger rods H. which latter at their lower ends are threaded. as indicated at 18, for the reception of a nut 19, and this nut may be held against accidental displacement by a rotter pin 20 passed through the threaded portion of the rod or byany other suitable means. although a cotter pin is to be preferred because of its simplicity. The frame It; between the enlargements 17 is in the form of a web 21- and projecting from this web are a number of fingers each of which maybe laterally expanded on the upper edge. as shown at and may also rise slightly toward the ends remote from the web :21 with relation to the normal position of the frame 16 when mounted on the suspension rods 14. The free end of each linger '32 may be arranged at a slightly ris ing angle with relation to the rest of the linger. as indicated at 24.

The space between any two adjacent lingers 22 is such that a sucker rod 11 may be introduced between the fingers. but the sucker rods are customarily enlarged at their screw threaded ends and are also provided with tool receiving portions. The space between adjacent lingers 2'2 is so related to the enlarged ends of the sucker rods thatsuch enlarged portions will engage the fingers while the main portion of the sucker rod wwlion is between such fingers. wherefore llnsmelter rod section is sustained by the enlarged portion, while the main portion of the rod is in pendent relation to the fingers upholding it.

By properly positioning the frame 16 with relation to the tubing rope 5 the sucker rod sections as they are withdrawn from the well tubing 8 may be elevated to a suitable height and then unscrewed from the portion of the sucker rod still within the well and then elevated to one side sufiiciently to engage between appropriate fingers 22, when the rod may be slightly lowered until the enlarged end of the portion of the sucker rod engaging between the fingers rests on said fingers. The sucker rod sections are or may be all of approximately the same length and the frame 16 may be sufiiciently extensive to receive all the rod sections which are needed for a well. In this way the sucker rod sections as removed from the well are hung ,pendently from their then upper ends sufliciently to one side to be out of the way but still in such relation to the well that they may be readily applied when the sucker rod is being inserted into the well. By this means all liability of bending or kinking the sucker rod is avoided, and consequently the rod is at all times straight, the sections mav be readily screwed together as needed, and wear and friction clue to bending or kinking of the rod sections is wholly avoided.

Instead of having a. straight supporting frame as in Figs. 1, 2 and 3, a circular frame may be employed, in which case but one suspension rod 14 is employed. There is then provided a spider support comprising a hub 25 suitably bored to receive the suspension rod l-l, which, like the structure shown in Figs. 1, 2 and 3, is provided with a nut 19 to be applied toits threaded end 18 and a cotter pin 20 is used to hold the nut in place. The hub carries a radially disposed plate 26 slightly dished toward the hub, and this plate ist'ormed with a circular series of entering slots 27 extending from the periphery tonear the hub. Intermediate of the slots 27 are other entering radial slots 28 extending from the periphery toward the hub. but to a less extent than the slots 27, while between the slots 27 and 28 are radially entering slots 29 commencing at the periphery and extending toward the hub to a still less distance. The number of slots and their disposition depends upon the diameter of the supporting plate '26, d as these slots are of the same width which may beequal to the width between two fingers 22 of the 'form shown in Figs. 1. 2 and 3. their extent toward the hub is limited by the approach of the slots and the necessity of having the plate of requisite strength to with stand the strain of the weight of the sucker rods. To strengthen the plate it is provided on the under side with webs 30. The slots 27, 28 and 29 define fingers 31 between them and each finger has a short upturned end 32 serving in conjunction with the dished form of the plate to prevent accidental escape of any of the sucker rod sections which may be lodged in the slots 27, 28 or 29. Those portions of the plate 26 defined by the slots 27, 28 and 29 are also in effect lingers, between which the sucker rod sections are inserted the same as in the form shown in Figs. 2 and 3. The capacity of the plate 26 may be quite large due to the numerous slots, some of which need only be long enough to accommodate one sucker rod section, and the others may be long enough to accommodate several sucker rod sections each. One advantage of the plate form of support for the sucker rods is that it may be rotated upon the suspension rod 9 as an axis and any of the rods carried by the rotatable plate may be brought adjacent the well tubing so as to require but a minimum of movement to bring the rod into position to enter the well, or on being removed therefrom to enter an appropriate slot in the plate. The rotatable carrier for the sucker rods illustrated in Figs. 4 and 5 is also more compact than the type shown in Figs. 2 and 3. I

The suspension rod 14: with its engaging hook 15 designed to engage lover a-crown block 3 may be readily applied to existing forms of derricks without interference therewith and without the necessity of any change in the structure of the derrick even to the extent of boring bolt holes, and when the suspension device is not in use it may be readily removed and placed out of the way at some point of storage. Of course,'other forms of suspension, for the supporting frame, than the rod 14 with the hook end 15 may be'used'. By providing slots of varying lengths in the circular frame form of the device the rods occupy but a minimum of space and therefore offer no unnecessary obstruction for the tubing elevator to catch on and do damage. Furthermore, the frame will accommodate more rod sections and may therefore be of less diameter and inter fere less with the tools used about the well than if the slots were all of the same length.

When the rod sections are being placed in or taken from the well, a workman stands in the derrick near the rod supporting frame and pulls the hoisted rod over into the frame when the rod is lowereduntil seated, after which the elevator is disconnected and lowered from the next rod section. For placing the rod sections in tion is reversed.

What is claimed is:

1. The combination with a well derrick having a crown block and pulley atthe top,

a bull wheel at the bottom, and a hoisting the well the operaseats which open inwardly toward the cable,

said seats being adapted to receive the sucker rod sections, whereby the seats of the frame may besuccessively brought into juxtaposition to the hoisting cable so as to permit the ends of the sucker rod sections to be carried into the seats, causing said sections to be suspended from the frame with their lower ends free of any support.

2. The combination with a well derrick having a crown block and pulley at the top, a bull wheel at the bottom and a hoisting cable leading from the bull wheel-over said pulley down into the well, a hanger rod formed at its upper end to rigidly engage with the crown block-and extending downwardly within the derrick, a frame mounted on the lower end of the rod and located at the sucker rod sections directly from said cable, said frame being arranged above the bottom of the derrick at a sufiicient distance so that when the sucker rod sections are car-.

ried into the seats from the hoisting cable, they are suspended from their upper ends with their lower ends free.

3. The combination with a well derrick, of a suspension member for sucker-rod sections sustained from the top of the derrick in elevated relation to the bottom portion of the derrick and also to one side of the center line of the well, said suspension member having open seats for suspending suckerrod sections by their upper ends, said seats being open toward the middle portion of the derrick .to receive the sucker rod sections directly from the hoisting cable as they are lifted from the well and to present them for insertion into the well,the elevation of the suspension member being such that the lower ends of the suspended sucker rod sections are free from support.

In testimony that I claim the foregoing CLARENCE L. PARKER.
